如何实现控件+查找与浏览器相同的功能到特定的div [英] how to implement control+find functionality same as browser to a particular div

问题描述

我有一个带有一些文本的div和一个div上面的文本框，我想每当用户键入一些文本时，用户输入的文本应该是突出显示它也应该显示macthing记录的数量为（2/20）与我们在浏览器中按ctl + f时的操作相同。



我有发现突出显示jquery插件，但它确实没有显示记录为（2 of 20）。只是突出显示文本。

Hi,

I have a div with some text and a textbox above that div ,i want whenever user type some text ,the text enetered by the user should be highlighted and it should also show number of macthing records as ( 2 of 20) same as what we do in a browser when we press ctl+f .

I have found highlight jquery plugin but it does show no of records as (2 of 20 ) .it just highlight text.

jQuery.fn.highlight = function (pat) {
    function innerHighlight(node, pat) {
        var skip = 0;
        if (node.nodeType == 3) {
            var pos = node.data.toUpperCase().indexOf(pat);
            if (pos >= 0) {
                var spannode = document.createElement('span');
                spannode.className = 'highlight';
                var middlebit = node.splitText(pos);
                var endbit = middlebit.splitText(pat.length);
                var middleclone = middlebit.cloneNode(true);
                spannode.appendChild(middleclone);
                middlebit.parentNode.replaceChild(spannode, middlebit);
                skip = 1;
            }
        }
        else if (node.nodeType == 1 && node.childNodes && !/(script|style)/i.test(node.tagName)) {
            for (var i = 0; i < node.childNodes.length; ++i) {
                i += innerHighlight(node.childNodes[i], pat);
            }
        }
        return skip;
    }
    return this.each(function () {
        innerHighlight(this, pat.toUpperCase());
    });
};
